The end of August can only mean one thing: The beginning of September. It’s true that time’s unceasing march reminds us that at each new moment we’re older than we’ve ever been. But as inevitably as one second follows the next, you know that Macworld’s Weekly Wrap will once again appear come week’s end, offering up pointers to some of our biggest stories from the past seven days. Let’s get to it.

The password is: Advice

If some nefarious miscreant is going to break into your Dropbox account, at least make him work for it. We step you through enabling Dropbox’s new two-step authentication process. It makes you wonder: If someone invents a new dance craze inspired by such two-factor authentication, will it be called the Two-Step Two-Step?

If you store your iTunes music library on a separate drive, you might find that the app sometimes chooses to forget all about where you store your library and instead reset your library location. There’s a solution for that. Besides cursing, I mean.

We figured out how to use your iPad with AT&T’s new Mobile Share plans. At least, we think we did; AT&T called us and said that maybe the customer service representative we spoke to got some details wrong.

Editor: There’s a new Final Draft Writer app for iPad. How do tell our readers about it? How!?

[He begins weeping.]

Serenity Caldwell: Keep it together, man! We’ll reach out to some professional screenwriters for their feedback on the app, and mix in a little hands-on experience, too. Readers will love it! We can make the headline, say, Screenwriters react to new Final Draft Writer iPad app.

Other apps we looked at this week included TypeStyler for fancy text, JPEGmini for slimming photos, and Desktop Tidy for investigating fusion. OK, OK, that last one actually helps you keep your Mac’s desktop clear of cruft.

And as part of a new series where we’ll look at some of the long-running, most venerable Mac apps around, Glenn Fleishman reminisced about 21 years with Photoshop. By my calculations, that means Glenn started using the software when he was -2 years old.
